Reaction Arrow

Use the Reaction Arrow tool to draw a variety of reaction arrows. Click
on the button alongside the arrow that you want to use followed by OK.

Arrows are drawn, from the tail to the arrowhead, by clicking, holding,
and dragging the cursor. Reaction roles are automatically assigned to
fragments when an arrow has been drawn. If reaction roles are not assigned,
erase and redraw the arrow in closer proximity to the fragments.

Shortcuts

Click right on the Reaction Arrow to select the default arrow.

Note: Reaction tools are
disabled for normal drawing modes. Select the Rxn
Tool from the toolbar or choose Show
Reactions from the Display Menu.
